B. use ejbSelect methods to access fields of a bean instance

Looking at the option, it is not clear if it is referring to cmp fields or static final fields. Anyway, ejbSelect method can still access cmp fields, when called from business methods that are defined in component interface.

Thanks keerthi for the reply,

But I feel that option A is also correct
A. use ejbSelect methods within ejbHome methods to return entities
We can use ejbSelect methods within ejbHome methods right.

Correct me if I am wrong.

Thanks

Yes. You are right.

Actually I have use ejbSelect<method> within an ejbHome<method> I think this is not clear.

see example :

public Collection ejbHomeListAllUserWithActiveCart()throws FinderException{
Collection list = null;
list = ejbSelectAllUserWithActiveCart();
return list;
}
